The island was roughly surveyed by Discovery Investigations personnel in 1927.

The name, derived from epsilon, the fifth letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of the Melchior Islands by Argentine expeditions in 1942 and 1943.
